C＃将行与先前的行比较 [英] C# Compare Rows with Previous Ones

问题描述

您好，我想将数据表的单元格值与之前的单元格值进行比较，并显示相似数据的单元格值。可以使用嵌套的for循环来完成它，但它的复杂性是O（n ^ 3）。有没有更好的方法呢？



例如

ON =对象名称

A＃=属性

ON -A1-A2-A3-A4

A --- 2 --- 3 --- 2 --- 1

B --- 1 --- 3 --- 3 --- 2

C --- 2 --- 1 --- 1 --- 1

D --- 3 --- 2 --- 2 --- 1



结果是

答：0

BA：A2

CA：A1-A4

CB：0

DA：A3-A4

DB：0

DC：A4

感谢您的帮助。

Hello, I want to compare cell values of a datatable with the previous ones and display attribute number of the similar ones. It is possible to do it using nested for-loops but its complexity is O(n^3). Is there a better way to do it?

For example
ON = Object Name
A# = Attribute
ON-A1-A2-A3-A4
A---2---3---2---1
B---1---3---3---2
C---2---1---1---1
D---3---2---2---1

Here the result is
A : 0
B-A: A2
C-A: A1-A4
C-B: 0
D-A: A3-A4
D-B: 0
D-C: A4
Thanks for the help.
